GEARING.

Specification of Letters Patent.

Patented Sept. 25, 1906.

Application filed March 16, 1906. Serial No. 306,421.

To all whom it may concern;

Be it known that I, JOSEPH KENNARD KooNs, a citizen of the United States. and a resident of Montgomery, in the county of Lycoming and State of Pennsylvania, ave made certain new and useful Improvements in Gearing, of which the following is a specification.

My invention is an improvement in gearing and it consists in certain novel constructions and combinations of parts hereinafter described and claimed.

Referring to the drawings forming a part thereof, Figure 1 is a rear view ofmy improved gearing. Fig. 2 is a'plan view. Fig. 3 is a front view. Fig. 4 is a section on the line 4 4 of Fig. 2. Fig. 5 is a section on the line 5 5 of Fig. 2. Fig. 6 is a section on the line 6 6 of Fig. 2. Fig. 7 is a section on the line 7 7 of Fig. 2, and Fig. Sis a section on the line 8 8 of the same figure.

In the present embodiment of my invention the gearing is mounted in a bracket A, comprising a base a and upturned sides a, the said si'des sloping toward the front and provided with bearings a a a a for the reception of the driving and transmission shafts, respectively.

The driving-shaft B, journaled in the bearings a a is provided with a longitudinal opening having oppositely-arranged parallel 7 slots 12 communicating therewith. A pin b is slidably mounted in the opening and-is provided with oppositely-disposed lugs or eye b projecting through the slots, the outer end of the pin being provided with a plurality of circular notches b for a purpose to be hereinafter described. The drivingshaft B is provided with a plurality of loose gears, comprising a small gear I), a medium gear b and a large gear I), and with a fixed gear b of the same diameter as the large gear I).

The transmission mechanism 0 comprises a wheel 0", having a flange 0, provided with external teeth 0, meshing with the gear I) on the driving-shaft. The flange is also provided with internal teeth 0 and the wheel is provided with a bearing-pin c resting in the bearing a. The inner side of the wheel is provided with a recess c for receiving a pin 0 upon the body portion 0 of a bracket 0 the said bracket having a foot 0 secured to the base of the mounting-bracket A by the screws 0 Another pin 0 upon the opposite side of the body portion of the brac et from the pin c engages a recess 0 at the center of a wheel 0, the said wheel being also provided with a flan e 0, having external teeth 0, meshing wit the internal teeth 0 on the flange of the wheel 0, and with internal teeth 0 for a purpose to be hereinafter described. A roller c is provided with external teeth 0, meshing with the internal teeth of the flange e and with a bearing-pin c, resting in the bearing aof the mountingbracket. The external teeth 0 of the .wheel 0 also mesh with the intermediate gear 1) upon the driving-shaft, while the teeth 0 of the roller 0 mesh with the teeth of the large gear 6, the smooth part of the roller coming opposite the teeth of the fixed gear.

A counter-shaft D is j ournaled in brackets (1, connected with the rear of the frame, the said shaft having a longitudinal opening and being provided with longitudinal opposltelyarranged slots (1 communicating therewith. A pin d is slidably mounted within the longitudinal opening and is provided with lugs or keys d projecting through the slots, and the outer end of the pin is provided with a plurality of circular recesses or notches d for a purpose to be hereinafter described. Upon the counter-shaft D is secured a fixed gear (1, meshing with the fixed ear of the driving-shaft, and a loose gear meshing with the external teeth of the wheel 0, forming a part of the transmission mechanism. The loose gear (1 is prevented from moving longitudinally of the counter-shaft by collars (1, arranged upon either side thereof and secured to the shaft by the screw (1.

Each of the gears upon the driving-shaft and each of the gears upon the counter-shaft is provided at each end around the opening through which passes the shaft with a circu lar recess b d and with oppositely-arranged keyways b d, whereby to permit the passage of the lugs or keys on the pins 1) d.

The recesses of two adjacent gears coact to form a passage sufficient to permit the rotation of the keys or lugs upon the pins between the gears without engaging them. The provision of the recess prevents the simultaneo'us engagement of any two gears upon the same shaft.

A wheel G, provided on a part of its periphery with teeth 9 for engaging the circular notches of the pins b d, is ournaled in brackets g, connected to the mounting by a screw and is provided at one end with a square portion 9 for engagement by a Wrench 9 It will be evident from the description that when the wheel G is rotated in either direction one of the pins will be moved inwardly and the other will be moved outwardly.

For the purpose of locking the pin b to prevent movement thereof I provide a casing H integral with an arm 72., secured to the mounting by screws k and provided with a in if, slid ably mounted therein, the pin having, a tooth h for engaging one of the circular recesses or notches and a handle 7)? for manipulating the pin. Upon-the face of the wheel G are arranged a plurality of cams '9, adapted to engage the handle it for retaining the pin 71- in such position that the tooth it will be out of contact with the notches b of the pin 1).

From an inspection of Fig. 4 it will be seen that when the ke (1 upon the pin (1 is just entering into loc ing engagement with the loose gear 11 upon the counter-shaft D the teeth of the gear-wheel G are disengaged from the in b and the camsg are in such position, ig. 3, that the handle it of the pin it will drop therebetween, thus automatically locking the pin b and preventing further movement of the same until the key again disengages the loose gear from the shaft. When the loose gear d is locked to the counter-shaft, it is impossible to connect any of the locse'gears with the driving-shaft; but when said loose. gear d is disconnected the driving-shaft maybe connected with any of its loose gears. The locking-pin b is retained out of engagementwith the pm I) at all times,

except when the counter-shaft is connected with its loose gear.

By properly manipulating the wheel G any of the gears b b b ma be connected with the driving-shaft, or al of the loose gears may-be disconnected from the driving-shaft and the loose gear connected with the counter-shaft whereby to reverse the direction of rotation of the transmission mechanism.

The peculiar construction of the transmission mechanism permits of a sharper graduation of the ratio between the differential gears and at the same time provides a certain amount of flexibility in the connection between said shaft and the drivin -shaft, while the arrangement of the pins earing the keys absolutely prevents the simultaneous coupling of the counter-shaft and -the driving-shaft to the transmission mechanism.

In Fig. 4 the loose gears on the drivingshaft are shown-as provided with ribs t, .fitting into grooves '1'. on the adjacent gear, whereby to strengthen said gears.

Having thus described my invention, what. I claim as new, and desire to secure by Let ters Patent, is
